An ubiquitous species, being, I think, 

 almost uniformly distributed throughout 

 tlie mainland and islands, and common 

 from sea-level to an altitude of 2500 

 feet. Shows great variation in colour, 

 particularly in the south and west ; 

 and specimens from milk-white to 

 almost jet-black are generally to be 

 found in these districts. In some places, 

 usually in the maritime counties, the 

 beautiful var. lilacina occurs commonly, 

 and more often than not, in colonies ; 

 while the mountain form is almost 

 invariably of a dusky brown colour'. 

 Specimens which I have collected on 

 Tory Island, West Donegal, were all of 

 this " mountain " form, with the addi- 

 tion of two darker brown stripes, one 

 on each side of the shield.

This was formerly regarded as a rare 

 species in Ireland, and appears to have 

 been unknown to Thompson or his cor- 

 respondents. In reality it is quite 

 common, and is generally distributed, 

 being found in moist woods and wher- 

 ever suitable marshy ground exists. 

 From the comparative dryness of parts 

 of the eastern and central areas, it is 

 perhaps more abundant in the southern, 

 western, and northern counties. It lives 

 on most of the western islands, whose 

 moist climate is eminently suitable for 

 its existence. In the Botanic Gardens, 

 Glasiievin, and in some nurseries, a 

 rather peculiar form, apparently of this 

 species, has been introduced with foreign 

 plants into the hot-houses. It differs 

 from oui native examples in being of a 

 deep slate-purple colour instead of the 

 usual brown.
